  1. * test significant at p < 0.05, at p < 0.01 after Holm-adjustment. Bold when high correlations (rs > 0.70); italic when moderate (0.70 > rs > 0.50); rs values lower than 0.50 are low
  2. Δ: changes (post-pre); MT: movement time (s); Curvl: trajectory directness; Vmax: peak velocity (cm/s); T%Vmax: peak velocity (%); NVP: number of velocity peaks; LDJ: log dimensionless jerk; ShFE: range shoulder flexion/extension (deg); ShAA: range shoulder abduction/adduction (deg); ElFE: range elbow flexion/extension (deg); Th: range of thorax rotation (deg); TExc: maximum distance travelled by the clavicle marker (cm)
